The Reuters news service has put together a collection of what it considers to be its best technology and science related photographs taken in 2015. Including robots, 3D printing, solar aircraft, a remarkable face transplant and more, here are some of those pictures.

In need a of recharge, a "Nao" humanoid robot by Aldebaran Robotics sits in a corner during a presentation at a Tokyo bank on April 13, 2015. The robot is able to offer customers information about banking services in Japanese, English or Chinese.

Inigo Munoz Elorza of Spain and Stefan Dobrovolny of Austria collect rock samples during a simulated Mars mission on Tyrolean glaciers in Kaunertal, Austria on Aug. 7. The Austrian Space Forum was sending researchers there to practice weight-less walking in spacesuits on a glacier that resembles the terrain on Mars.

A United Launch Alliance Atlas V 551 rocket blasts off from Cape Canaveral in Florida on Jan. 20. The unmanned rocket carried a communications satellite designed to provide cellular-like voice and data services to U.S. military forces around the world. The picture was taken using long exposure, looking over the campus of Florida Institute of Technologies.

Belgian chocolatier Dominique Persoone snorts cocoa powder off his Chocolate Shooter in his factory in Bruges on Feb. 3. Inspired by a device his grandfather used to propel tobacco snuff up his nose, Persoone created the chocolate-sniffing device for a Rolling Stones party in 2007. Though he never imagined demand would stretch much beyond the rock 'n' roll scene, he has now sold 25,000.

Forced by bad weather to change course, the Solar Impulse 2, a solar powered plane, circles above Nagoya airport in Japan before a landing on June 1. Subsequent problems with the plane’s batteries forced repairs that will delay resumption of its 22,000-mile flight around the world until next spring.

Former mechanic Xu Yanhua, 32, paralyzed from the shoulders down after a workplace injury, uses an extended stylus to type on a tablet as he runs his online store on his bed in China on June 24. According to local media, the family could not afford proper medical treatment for Xu, who has been operating an online store to sell socks in hopes of earning money to help out.

Yamaha Motor Co displays the company's prototype of a motorcycle-riding robot 'MOTOBOT Ver. 1' at the Tokyo Motor Show on Nov. 2. Visitors reportedly stopped in their tracks to get a photo. The humanoid robot can analyze its location and route through GPS. It can travel as fast as 75 mph and has two small protracted assist wheels on either side to help keep its balance when riding at slower speeds.

Data storage servers are seen at Advania's Thor Data Center in Hafnarfjordur, Iceland on Aug. 7. As that country emerges from financial isolation, Iceland is trying to make a name for itself in the data center business.

At the Augmented Human International Conference in Singapore March 10, a visitor puts on "Truth?" a pair of goggles made by students from Keio University in Japan that projects the "true emotions" of a person by monitoring the patterns of his or her heartbeat. It was part of a design competition showcasing of wearable technology.

The shock wave of a T-38C supersonic jet flying over the Mojave Desert in California is seen in an undated NASA schlieren image released Aug. 25. Researchers used NASA-developed image processing software to remove the desert background, then combined and averaged multiple frames to produce a clear picture of the shock waves. Schlieren imaging reveals shock waves due to air density gradient and the accompanying change in refractive index, according to a NASA news release.

Dr. Eduardo D. Rodriguez of the NYU Langone Medical Center holds a news conference to announce the successful completion of the most extensive face transplant to date on Nov. 16. Rodriguez led the surgical team on 41-year-old Patrick Hardison, a Mississippi firefighter whose face was badly burned in 2001. More than 100 doctors and support staff took part in the 26-hour operation.

The NASA Jet Propulsion Lab team's RoboSimian robot turns on a valve at a simulated disaster-response course during day one of DARPA’s Robotics Challenge finals in Pomona, California, June 5. The event drew robotic teams from around the world to compete on a series of eight challenges.

A visitor tries the flight simulator Birdly at the exhibition "Animated Wonderworlds" at the Museum fuer Gestaltung (Museum for Design) in Zurich, Nov. 17. Birdly simulates the flight of a red kite over New York City, controlled by the entire body of the user. The flight simulator was developed by scientists at Zurich University of the Arts.

A humanoid robot called Han, developed by Hanson Robotics, reacts as the controller commands it via a mobile phone to make a facial expression during an electronics show in Hong Kong April 18. According to its maker, the robot's skin is made out of a material called Frubber, an elastic polymer that mimics human skin. It is installed with about 40 motors on its face which help create various expressions. Han can answer simple questions and staff said it can be used in the field of customer service.
